In the game, sending a radio report increases the probablily of an enemy airstrike being sent your way. The "Airstrike.cfg" file has an entry for "Enemy Air Strike Probability Increase on Radio Message Sent". However, I can't swear that there is an increased probability of enemy ships detecting you as well. Anecdotal evidence from different posters on this forum would seem to suggest that it does.

In an earlier post, Kpt. Lehmann had this to say on the subject:
"Radio Direction Finding: Though there are more than a few
who feel that this is a broken function in SH3... I believe a
representation of it exists to some degree in-game. I can
only offer my own experiences in reporting this means of detection
by the enemy and by the apparently active values
one can find in the Airstrike Configuration file. (At the
very least, the enemy AI will send some sort of distress
signal... which we can all attest to having attacked single
merchies only to have a DD or enemy aircraft attack soon after)."


As to whether that is historically correct for as early as October 1939 I will leave to someone more knowledgeable on the subject.
